1. A liquid level detector for use in containers of electrically conductive liquids wherein said detector is installed vertically comprising:

  • a) a sheath having an open lower end defined by a rim for contacting a liquid;

    b) at least one vertically extending notch in said rim;

    said notch terminating in a shoulder at its upper end;

    c) an electrically conductive probe positioned within said sheath and being spaced apart therefrom, said probe having a tip positioned vertically between said rim and the shoulder of said notch;

    d) an insulating seal between said probe and said sheath hermetically sealing the tube at a predetermined distance vertically above the tip of said probe, said seal holding and positioning said probe within said sheath;

    e) a first electrical conductor connected to the upper end of said probe and a second electrical conductor for electrically establishing a conductive path with a liquid into which said probe may be inserted, each of said conductors being adapted to be connected to a module for sensing a complete circuit between the probe and liquid.
